I now have fonts! I added the font directories found by /usr/sbin/chkfontpath to the Files Section of the /etc/X11/xorg.conf and following a restart things began to work.

The system startup script for xfs makes reference to a /tmp/.font-unix directory. An error message appears on the boot details screen to the effect that lstat reports /tmp/.font-unix does not exist but I can find no reference to this error in any of the logs. After startup I can find that directory but it is empty.

I have no idea how this is supposed to work but I suspect that the dynamic discovery and addition of the font directories is failing for some reason.
